iro ALL WHOM 1r MAY coNennN: y Y

Beit known that I, 'HENRI-YIHEIMERLE, of the eityot Butalo, county of Erie, and State Of-New York, have invented a certain new and 'improved Beer-Cooler; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingdrawingsmaking a part,of this spcification,

in whichl' Figure Ijs averticai section, Figure II is a. side elevation, Figure III is a. transverse vertical section of my improved coolers.

The nature of my invention consists, rst, in the combination and arrangement of a fiat tank or reservoir, standingon end, and filled with Coldwater, with a pipe, or series of pipes or conductors placed therein, at a slight incline, in such manner that the liquid to hc cooled may, when introduced into the top end of said pipes, slowly descend throughlthe conductors to the bottom of the tank, and during such descent be cooled; second, in the combination andnrrangeinent, withsaid tank and conductors, of annmber of open troughs arranged upon the outside of the tank, and connected by means of the pipes or conductors in such manner that the liquid to be cooled, in its descent, will intermittently be "exposed to the atmosphere for evaporation and condensation.

Letters .of like name and'kindrefer to like parts in each of the figures. v f

lA represents an oblong tanker reservoir, which is placed on end, and the dimensions of which will be about eight feet high, three feet long, and four inches 'wider This tank is made portable, and on account of its peculiar shape does not occupy a very large space.` This tank is filled with cold water from a supply-tank placed at an elevation above the top of the tank A, which supply-tank is connected with the bottom 'of the `tank by means of Aa pipe, as shown at a. agis a discharge-pipe near the top of the reservoir A, through which the water Aiscarried off from the surface; The water, its it enters at the bottom,and becomes warm by contact with the hot conductors, will rise to the surface and be discharged through the pipe a2. B B represent the pipes or conductors, whichcontain the liquid to be cooled. They are arranged one above the other, nearly parallel, with Y a. slight inclination to one sidc,'in such manner asto allow the liquid to'desccndslowly from the top to .the-bot.- tom. These cond-actors may either be connected by elbows or semicircular joints within the tank, as shown by red dotted lines in FigrI, or they may open at'each end into the top and bottom of a trough or open box, C,

rmly connected to the outside of the tank A. The liquid to be cooled will, in its descent, be intermittently introduced 4into these open troughs, and by this means the vapor collected inthe pipes B will be condensed or allowed to escape.

In Fig. III, two of these coolers are represented as connected together; which is rendered necessary in large breweries or distilleries, where the'capacity of one cooler is insuliicient.

What 'I claim as my invention, and desire to'secure by Letters Patent, is

1. The combination and arrangement of theupright tank A with the inclined pipes or conductorsB, for the purpose und substantially asherein described. l

2. The combination and arrangement ofthe tank A, conductors B, and open troughs C, constructed as and for the purpose herein described. v Y l HENRY HEIMERLE. Witnesses:
